- Hello. This is just position coordinate transformation. For vectors, transformations are executed with matrix multiplication. For example, from polar to cartesian:

[Ax; Ay] = [cos phi -sin phi ; sin phi cos phi ] * [Ar; Aphi]

- Comment/Request
- Theta is the angle from the positive z-axis to the xy-plane in the ISO (physics) convention. I think it would be beneficial to mention that this representation used here is following the mathematics convention.
